glUV: A global UV-B radiation dataset for macroecological studies
glUV is a set of climate surfaces containing information on various aspects of the global distribution of ultraviolet-B radiation (UV-B). The data represents a potentially useful addition to existing climate datasets (e.g. 
CliMond, WorldClim) and may help refine macroecological analyses and bioclimatic modelling.
glUV may help address research questions related to the range-limiting capacities UV-B radiation has on terrestrial and marine life. The applicability of glUV is not limited to bioclimatic modelling and may be used for planning experiments along UV-B gradients or for reanalysing existing species distributions. Studies investigating the intra-annual variability of UV-B radiation may also benefit from implementing the provided monthly mean UV-B datasets used to derive the bioclimatic UV-B variables. glUV may even find applications outside the realms of ecology and biology, for example, in estimating material degradation rates or addressing UV-B related health issues.
